THOMAS STUBBS BAYLES, OF TORONTO, CANADA.

HOT-WATER HEATER.

SPECIFICATION forming part of Letters Patent No. 581,190, dated April 20, 1897. Application filed January 31, 1896. Serial No. 577,573. (No model.) Patented in Canada April 3,189 5,N0.4-.8,593.

1 '0 at whom it may concern.-

Be it known that LTHoMAs STUBBs BAYLES, of the city of Toronto, in the county of York, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Hot-Water Heaters, of which the following is a specification.

My invention relates to improvements in hot-water heaters, patented to me in Canada under No. 48,593 on the 3d day of April, 1895; and the object of theinvention is to provide a simple, cheaply-constructed, compact, and economical hot-water heater; and it consists, essentially, of a plurality of hot-water sections connected together and having a central flowchamber of peculiar construction, which flowchamber is connected to the sections, and a spirally-formed bottom section surmounted on a water-jacket surrounding the flre-pot, suitable passage ways being provided for connecting together the water-jacket spiral section and other sections and flow-chamber, all the sections being connected together by a central bolt and the construction of the fiues being arranged as hereinafter more particularly explained.

The drawing represents a sectional perspective View of a heater constructed in ac cordance with my invention.

A is the water-jacket, which surrounds the fire-pot, and B is the return-pipe, which is connected to the water-jacket, as shown.

C is the bottom section, which is mounted upon the Water-jacket andis formed with a spiral passage-way C, starting at the periphery at c, where it is connected by the opening a with the water-jacket A, and separated from the rest of the spiral section by the Wall 0 and ending at the center at 0 Where a well C is formed. The top C of the section is made preferably perfectly fiat, so that the top of the spiral passage-way is substantially rectangular. The bottom of the section C is made spirally semitubular, so as to provide a large heating-surface.

D, E, F, and G are the different sections of the heater, which are mounted in the order named above the section C. The section D has a downwardly-extending flange d at its periphery, which fits within the edge of the section C and is formed with a central opening D. I

c is an upwardly-extending flange forming part of the section C. Upon the flange 0 fits a similar flange d, extending downwardly g ter of the partition d is curved, as shown.

D is an opening leading into the hot-water section D.

D is a partition diametrically opposite the center of the opening D and extending from the top to the bottom plate from the opening D to the exterior of the section.

D areopenings situated one at each side of the partition D E is the section next above the section D, which is formed with flanges e 8 e partition 6 opening E partition E and openings E corresponding with flanges d d d partition (1 opening D partition D and openings D respectively, of the section D.

F is the next section above, which is provided with the flanges f f f partition f opening F partition F and openings F corresponding with flanges d (1 d partition d opening D partition D and openings D respectively, of the section D.

G is the next section above, which is provided with the flanges g g 9 partition 9 opening G partition G and openings G corresponding with flanges d d d partition d opening D partition D and openings B, respectively, of the section D. The section G is also provided with a top plate 9 extending from the partition 9 over the opposite half of the central chamber C The top of the chamber C has connected to it a distributing head or chamber H, to which the flowpipes 72 are connected.

I is the dome for the top of the hot-water heater, and J is the smoke-pipe. The bottom of the well C in the center of the section C is formed with a recess 0 From the center of this recess extends a bolt K, which passes up through the center of the flowchamber C through the top of the distributing-chamber H, where a nut is provided on the top of the bolt, whereby the several sections are secured firmly together.

It will be seen that the partition formed of the several sections hereinbefore described, is curved so as to permit of the passage of the bolt.

All the fiangeshereinbefore mentioned are necessarily made water-tight.

L are flues arranged around the circumferential edge of the section 0, preferably to the inside thereof, and leading from the firepot to the space between the section 0 and section D.

L are tlucs which extend through the sections D and F around the low-chamber The fines L are located, preferably, in prox imity to such flow-chamber.

L are fines which extend through the sections E and G near the periphery thereof.

The flame and heat pass upwardly through the fines L, L, and I alternately in a zigzag direction, so that they are utilized to the bestadvantage in heating water in the sections. The bottom section C, being directly above the fire-pot, receives the intense heat, and the circulation of the water around the spiral ends in the central well C ,where the heated water rises and'passes through the openings throughout the several sections and passes off around the sections in two directions to the partitions diametrically opposite, whence it passes through the openings at each side of the partitions into the fiowchamber C", through which it rises to the head Il, whence it passes through the flow-pipe 7L throughout the building and returns by the pipe 13.

My heater having more heating-surface than any boiler for the size of grate-surface, it will be seen that in practice it will be more economical. The majority of other boilers have the flow-pipe at the back at the outside, where there is no heat having to travel therefrom to the front and back again. In my boiler the water circulates in the bottom spiral section to the center from the water-jacket around the fire-pot and in the other sections from one side of the flow-chamber to the other, never leaving the hottest part until passing out at the top. Each section is itself an independent heater, and the water does not require to traverse the successive sections above, and consequently there is the least possible friction, and the circulation issues from each section as fast as it becomes heated. All the sections are held together by one bolt, which in itself is of very economical construction.
